This is my exact strop, purchased from KSF. I first bought it for my Bark River brand knives because they are convex but used it on my other knives too and it works wonders. I always finish off with the strop after I touch my knives to my Arkansas hones or after a days worth of work in the woods. The best part is it dose not wear your knives down like a stone would.
Also your edge will last longer if you use a strop, a fine edge lasts longer than a coarse edge!
